> UBC in Vancouver has been suffering from issues of building misalignment
> because the Yahoo orthography is misaligned with the ground and suffers
> from distortion[1]. The City of Vancouver offers some mapping data [2]
> which can be used with OSM. I've taken 16 tiles that cover most of UBC
> and corrected most of the streets to these as these reflect the GPS
> traces, CanVec data, and my knowledge from being a student. They are
> also high resolution, being listed as 40cm, but I can easily make out
> smaller features.
> 
> I've also done some micro-mapping around the SUB, Buchanan, the Chan
> Center and Rose garden, and down by CEME.
> 
> As the process to convert the .ecw files is a long and computationally
> heavy one if anyone wants the resulting slippymap which can be used with
> the JOSM slippymap plugin and is regularly at UBC I could burn them onto
> a CD.
> 
> I also have all of Vancouver processing to make a slippymap, but it has
> only been about 25 hours so it is not finished yet. If anyone wants
> that, it'll take multiple DVDs. Of course, anyone could recreate it from
> the downloaded files but anticipate gdal2tiles taking about 30-40 hours
> on a good computer.

> If anyone notices misaligned streets at UBC and isn't able to get the
> Vancouver orthography working I'd appreciate knowing and I can align
> them.
